API links: more information on TYPO3 PHP classes 

Explicit links to api.typo3.org 

..  Explicit links

*   :api-class:`\TYPO3\CMS\Extbase\Routing\ExtbasePluginEnhancer`
*   :api-class:`In main <api-dev:\TYPO3\CMS\Extbase\Routing\ExtbasePluginEnhancer>`
*   :api-class:`In 11.5 <api-11:\TYPO3\CMS\Extbase\Routing\ExtbasePluginEnhancer>`
*   :api-class:`\TYPO3\CMS\Core\EventDispatcher\EventDispatcher
    <api:\TYPO3\CMS\Core\EventDispatcher\EventDispatcher>`

The links then look like this:

• ExtbasePluginEnhancer
• In main
• In 11.5
• \TYPO3\CMS\Core\EventDispatcher\EventDispatcher

Explicit links can use the interlink scheme to link to different TYPO3 versions. If not specified they also link to the typo3-core-preferred.

If you want to link directly to the source files on GitHub, you can use the :t3src: text role.

Implicit links to fully-qualified names 

Implicit links have the advantage that they show more information about the class or interface in a popover while they still offer a link to the API.

..  Implicit links using the :php: text role:

*   :php:`\TYPO3\CMS\Adminpanel\Controller\AjaxController`
*   :php:`\TYPO3\CMS\Core\Http\Dispatcher`
*   :php:`\TYPO3\CMS\Adminpanel\ModuleApi\ContentProviderInterface`
*   :php:`\TYPO3\CMS\Backend\Search\LiveSearch\SearchDemand\DemandPropertyName`
*   :php:`\TYPO3\CMS\Backend\Form\Behavior\OnFieldChangeTrait`
*   :php:`\Psr\Log\LoggerInterface`
*   :php:`\TYPO3Fluid\Fluid\Core\ViewHelper\AbstractViewHelper`
*   :php:`\MyVendor\MyExtension\FooBar`
*   :php:`\Foo\Bar\Something`

..  prevent help text being displayed

`This\\Is\\No\\Class`

The links then look like this:

• \TYPO3\CMS\Adminpanel\Controller\AjaxController
• \TYPO3\CMS\Core\Http\Dispatcher
• \TYPO3\CMS\Adminpanel\ModuleApi\ContentProviderInterface
• \TYPO3\CMS\Backend\Search\LiveSearch\SearchDemand\DemandPropertyName
• \TYPO3\CMS\Backend\Form\Behavior\OnFieldChangeTrait
• \Psr\Log\LoggerInterface
• \TYPO3Fluid\Fluid\Core\ViewHelper\AbstractViewHelper
• \MyVendor\MyExtension\FooBar
• \Foo\Bar\Something

This\Is\No\Class

As you can see, only classes in the namespace \TYPO3\CMS link to the API. We do display general information about some other namespaces that are commonly used in TYPO3 development. Example namespaces should always start with \MyVendor . Use \MyVendor\MyExtension for extensions and \MyVendor\MySitepackage for site packages, see Example names for extensions and site packages.

Implicit links are always referring to your typo3-core-preferred as set in the guides.xml.

Links to the API with the short class name 

Using the text role php-short you can display the short name of the class or interface within the text. Other than that it works just like the :php: text role.

..  Short PHP class names, still linking to the API:

*   :php-short:`\TYPO3\CMS\Adminpanel\Controller\AjaxController`
*   :php-short:`\TYPO3\CMS\Core\Http\Dispatcher`
*   :php-short:`\TYPO3\CMS\Adminpanel\ModuleApi\ContentProviderInterface`
*   :php-short:`\TYPO3\CMS\Backend\Search\LiveSearch\SearchDemand\DemandPropertyName`
*   :php-short:`\TYPO3\CMS\Backend\Form\Behavior\OnFieldChangeTrait`
*   :php-short:`\Psr\Log\LoggerInterface`
*   :php-short:`\TYPO3Fluid\Fluid\Core\ViewHelper\AbstractViewHelper`
*   :php-short:`\MyVendor\MyExtension\FooBar`
*   :php-short:`\Foo\Bar\Something`

The links then look like this:

• AjaxController
• Dispatcher
• ContentProviderInterface
• DemandPropertyName
• OnFieldChangeTrait
• LoggerInterface
• AbstractViewHelper
• FooBar
• Something
